它不能把脚放在椅子上
It’s a rainy day. A woman with a dog gets on a bus. It’s a big dog and its feet are not clean. The conductor(售票员) doesn’t want the dog to sit on the chair. But the woman says to the conductor, “Oh, I pay for my dog. Can he sit here like the other people?” The conductor looks at the dog and says, “Yes, Madam, but like the other people, he must not put his feet on the chair.”
